P2P技术的应用在现代网络系统中越来越普及,而云计算的出现给IT界带来了全新的挑战,因此,针对目前网络的发展现状,对P2P技术和云计算技术进行研究,提出了一种云计算环境中的P2P网络模型,这是云计算技术与P2P技术的一种结合。通过对使用P2P技术的网络中节点的处理能力、拥有的资源量、占据的带宽大小等进行评估,得出网络中各节点的层次结构并形成Hash环,然后利用一致性Hash算法在系统中对资源进行快速搜索。利用这种方法,由于每个节点只需要更新少量的信息就可以完成查询路由,从而实现了网络中资源的快速定位,提高了网络资源搜索的效率。
The application of P2P technology is becoming more and more popular in modern network systems. However, the emergence of cloud computing brings new challenges to the IT industry. Therefore, in view of the current development of the network, the research on P2P technology and cloud computing technology is proposed. Cloud computing environment in the P2P network model, which is a combination of cloud computing technology and P2P technology. By evaluating the processing capacity, the amount of resources owned and the bandwidth occupied by peers in the network using P2P technology, the hierarchical structure of each node in the network is formed and a Hash ring is formed. Then the Hash algorithm is used in the system Resources for quick search. With this method, each node only needs to update a small amount of information to complete the query routing, so as to realize the rapid positioning of resources in the network and improve the search efficiency of network resources.
